Dynamics of amine functionalized nanotubes/epoxy composites by dielectric relaxation spectroscopy Original Research Article

An investigation was conducted to determine how the aspect ratio of single walled carbon nanotubes (SWNTs) affects the dynamics of epoxy/amine networks at various stages of cross-linking. A new insight at the molecular level was obtained by employing a novel experimental approach based on simultaneous dielectric-infrared measurements. In particular, evidence was found which supports the formation of amine functionalized SWNTs, which affords a vehicle for the migration of intrinsic charges and provides a contribution to the overall conductivity.
